Area code 856 covers 33 rate centers across New Jersey. Communities served include Beaver Brook, Berlin, Blackwood, Bridgeton, Camden, and 28 more localities. Rate centers are the geographic building blocks telephone carriers use to determine local calling boundaries and to assign numbers when a business or individual requests a phone number in a specific city.
All numbers in the 856 area code observe Eastern Time (IANA timezone: America/New_York). Eastern Time is UTC−5 in winter (EST) and UTC−4 in summer (EDT). When placing a call to a 856 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within New Jersey, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 856 + 7-digit number for long-distance calls within North America. From outside the US or Canada, dial your country's international exit code followed by 1 856 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 856 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +18565550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
